For what it is, this amp is great. If you want to increase the output of your system with minimal effort (as I did when I bought this) then I highly recommend it. However if you are investing alot in high end speakers, don't cut corners. Buy a Boston acoustic multi-channel amp and some high quality speaker wire and re-wire those speakers! Stock wiring only allows so much power and is always of low quality. If I could do it all over again, this is what I would do.
